Definition of polarimeter in English:

polarimeter

noun

An instrument for measuring the polarization of light, and especially (in chemical analysis) for determining the effect of a substance in rotating the plane of polarization of light.

‘For remote-sensing applications, the goal is to produce pixel-integrated imaging polarimeters and spectral imagers directly on the IR FPA without the need for external optical filter elements or moving parts.’

‘Using polarimeters, which enable the polarization of the light received to be determined, astronomers hoped to be able to identify whether there was dust within the corona.’

‘Circular dichroism spectra were measured in a Jasco-600 polarimeter with a bandwidth of 2 nm.’

‘PDR Chiral make advanced laser polarimeters, but their site not just a glorified sales pitch for their instruments, as is so often the case with commercial web sites.’

‘Rotation angles were measured with a polarimeter on one-second integration interval.’

‘The literature is full of other, more complicated ways to measure optical anisotropy (involving polarimeters and ellipsometers, for example), usually using a combination of polarizers and retarders.’

‘They feature fast measurement speed (15 measurements per second), ideal for translating the polarimeter across samples and providing for an averaging of measurements for increased precision.’

‘Because existing spectrometers and polarimeters make use of mechanical scanning methods, they are unreliable and require a long time to acquire complete data sets.’

‘A 6-cm receiving system with a polarimeter, made by engineers of German Max-Planck-Institute for Radio-astronomy, has been installed to the 25 radio telescope in Urumqi, the capital of western China's Xinjiang Uygur Autonomous Region.’

‘The SMM satellite's coronagraph/polarimeter detected a large halo coronal mass ejection; the halo meant that the cloud was directed at Earth.’

‘A major difficulty in using microscopes for polarimeters is that most polarimeters purposely only collect light from a very small angle’

‘A nano-optic waveplate combined with a polarization beamsplitter can measure differential polarization and phase response in a compact polarimeter.’

‘All the CD experiments were done in a JASCO-J715 polarimeter (JASCO, Tokyo, Japan) in a 0.1-cm pathlength cell, with a slit width of 1 nm, response time of 4 s and scan speed of 50 nm/s. Each data point was an average of three accumulations.’

‘For example, the effect of acids and salts on a solution of an optically active substance such as nicotine could be followed by observing the rotation of the plane of polarised light through a polarimeter.’
